Abstract
Voltage regulator circuitry includes a first gain stage, a second gain stage, and a feedback stage. Feedback is provided between the feedback stage, the second gain stage, and the first gain stage in order to tightly regulate an output voltage of the voltage regulator circuitry such that the output voltage is independent of process variations present in the devices therein. The voltage regulator circuitry is fabricated using a pseudomorphic high electron mobility transistor (pHEMT) process in order to reduce the size thereof and provide short turn-on times and low quiescent current.
